maybe your missing the appsync 5.0.. install it from cydia.. add this repo cydia.hackulo.us
then from that repo you will find the appsync, install also the installous 4..
Aaaah, as I said, I'm a real newbie in this field. That almost sounds like a strange language to me.
I did notice that once I ran Absinthe, my iPad had Cydia installed, but I could never figure out what it was supposed to do. And I've found Cydia by using Google search, but haven't figured out how to actually download anything from any "repository" whatever that might be.
Haven't seen any "Help" menu nor manuals for Cydia.
Sorry to sound so elementary, but I got lost right at the beginning of your post
[Edit] Okay, later on. I googled both appsynch and installous, found them and downloaded them.
But how do I actually install them?
I've done all this through my iMac connected by ethernet modem, not by wifi iPad connection. Can I actually complete all this through this method, or must my iPad be connected by wifi to the internet, and then go through Cydia to download and install both of those apps, and after that, then I might be able to install the other stuff I've acquired? I'd like to be able to do it all right here at my computer, but I suppose if necessary, I'll get out somewhere for a wifi connection.
